NCP100ALPRPG

Overview

The NCP100ALPRPG is a precision adjustable shunt regulator in a TO-92 package. It features a programmable output voltage range of 0.9 V to 6.0 V with a reference accuracy of ±1.7% at 25°C and ±2.6% over the -40°C to 85°C temperature range. The device exhibits a sharp low current turn-on characteristic and a low dynamic impedance of 0.2 Ω across an operating current range of 100 µA to 20 mA. It operates within a cathode-to-anode voltage range of 0.9 V to 6.0 V and supports a continuous cathode current from 0.1 mA to 20 mA.

Feature Summary

• Programmable output voltage range spanning 0.9 V to 6.0 V for flexible low-voltage reference applications
• Tight voltage reference tolerance ensuring high precision across standard industrial temperature ranges
• Low dynamic output impedance providing stable regulation performance under varying load conditions
• Sharp low current turn-on characteristic enabling efficient operation in battery-powered systems

Applications

• Reference for single cell alkaline, NiCd, and NiMH battery applications
• Error amplifier for isolated low output voltage switching power supplies
• Battery powered consumer products requiring precise voltage monitoring
• Portable test equipment and instrumentation circuits

Procurement Notes

Verify the specific ordering suffix ALPRPG corresponds to the TO-92 leaded package configuration. Confirm compliance requirements such as RoHS status if applicable to your manufacturing process. Ensure the procurement channel provides valid traceability documentation for the component batch. Cross-reference the datasheet revision date against your design specifications to confirm parameter consistency.

Selection Notes

Select this component when a low voltage reference below 1.25 V is required. The TO-92 package is suitable for through-hole mounting where space constraints are less critical than cost efficiency. Consider the narrow operating current window of 100 µA to 20 mA when designing bias networks. Verify stability requirements regarding load capacitance and ESR for your specific feedback loop topology.

Part Context

This device belongs to the NCP100 series of sub-1.0 V precision adjustable shunt regulators. It serves as a specialized alternative to traditional Zener diodes and higher voltage references like the TL431 family. The series includes variants in both TO-92 and TSOP-5 packages to accommodate different PCB layout and thermal management needs.
